If I were to install a K&N Air Filter would I have to do any mods yo my bike like re-jet it or something like that?

you might need to install a larger main jet. With my experience with the 450r, it's good to rejet the quad even in stock form, as the stock jetting seems lame on the 04/05 (unsure of 06)
